Hello all!
I'm struggling and in need of some advice from someone with and understanding of soalr setups. I have 2x 250w panels- Voc 37.8v Isc 8.9A each - connected in parallel to a Tracer PTR4210AN 40A controller feeding 2x 6v Trojan batteries in series giving me 12v at 225Ah. Cable runs are 6mm, about 5mt from the PV to contoller and 1mt from the controller to the batteries.
Now, I know the sun is weak now so I shouldn't expect much from them but the controller shows (at best) 30 something v and 1.4A coming in from the PV array, most of the time though it's more like 0.9A. This is far below what I'd expected to get from this setup. Am I being unrealistic? Have I messed up on my selection of components?
I'm lost at to what could be wrong...
